The present disclosure relates to a movement device (10) for a helmet (12) for moving a first element (16) of the helmet (12) with respect to a second element (14) of the helmet (12). The movement device (10) includes a pivot element (24) for pivoting the first element (16) of the helmet with respect to the second element (14) of the helmet about an axis of rotation (X), and a pivot seat (25), in which the pivot element (24) is arranged. The pivot element (24) includes an eccentric portion or cam (26), and said seat includes a first seat region (30) adapted to receive said eccentric portion (26) and a second seat region (32) adapted to receive said eccentric portion (26). The first seat region (30) is in a position angularly offset and linearly translated with respect to said second seat region (32). A first position of the pivot element (24) corresponds to said first seat region (30) and a second position of the pivot element (24) corresponds to a second seat region (32), such that, when the eccentric portion (26) of the pivot element (24) passes from the first seat region (30) to the second seat region (32), the pivot element (24) performs both a rotation in order to compensate for angular offsetting between the second seat region (32) and the first seat region (30) and a translation to compensate for linear offsetting between the second seat region (32) and the first seat region (30). |
